Analytics Builder version

Use the 'main' branch for the current release or switch to the appropriate branch for Long-term support (LTS) / Maintenance releases.

System requirements

This script requires an installation of Python 3.7+ and runs on either Windows or Linux. To build extensions or configure Apama Plugin for Eclipse, a full installation of the latest Apama is required. If you do not already have access, then you can download the Apama Community Edition from Apama Downloads (shortly after the official Apama release date). If you choose to install Apama, you can skip the manual installation of Python, as it is shipped with Apama.

The apama-builder Docker image from Amazon ECR Public Gallery can also be used for building and managing extensions.

Note that Analytics Builder requires your Cumulocity IoT tenant to be subscribed to an 'apama-ctrl' microservice. The 'apama-ctrl-starter' microservice offers only restricted functionality and does not support custom blocks.

Documentation

The guide to writing blocks is available in the doc directory and there is ApamaDoc reference available.

Getting started

From an Apama command prompt:

• Run sample tests (Windows):

set ANALYTICS_BUILDER_SDK=%cd%
cd samples/tests
pysys run

• Run sample tests (Unix):

export ANALYTICS_BUILDER_SDK=`pwd`
cd samples/tests
pysys run

• Package samples as an extension and upload:

analytics_builder build extension --input samples/blocks --cumulocity_url <URL> --username <tenantID>/<username> --password <password> --name sample-blocks --restart

Note: After running the above command, the apama-ctrl microservice will be restarted.
